Therefore, when the push bar 1530 pushes the hour hand channel 1200 downward, the needle 1220 of the pushed hour hand channel 1200 may protrude by a predetermined length through the nozzle 25.

FIG. 5 is a diagram for describing an hour hand channel bundle B, according to an exemplary embodiment. Referring to the drawings, the hour hand channel bundle B includes a bundle body part 1100 and a plurality of hour hand channels 1200 coupled to the outer circumferential surface of the bundle body part 1100 so as to be slidable in the vertical direction.

In one embodiment, the bundle body portion 1100 may be composed of a cylindrical channel coupling portion 1110 and a head portion 1120 formed on the channel coupling portion 1110. The channel coupling unit 1110 and the head unit 1120 may be integrally formed or may be separately manufactured and combined. The channel coupling part 1110 and the head part 1120 have upper through holes formed therein, so that the central shaft 1550 penetrates through the bundle body part 1100 as shown in FIG. 2 or 3. Can be deployed.

A plurality of slide rails 1115 are formed on the outer circumferential surface of the channel coupling unit 1110 at radial equal intervals with respect to the central axis of the channel coupling unit 1110. In an embodiment, the slide rails 1115 are engraved long in the vertical direction, and the hour hand channels 1200 are slidably fitted to the slide rails 1115 in the vertical direction.

The head portion 1120 has a diameter larger than the diameter of the channel coupling portion 1110 and thus serves as a stopper to prevent the hour hand channels 1200 from rising upward.

As shown in FIG. 3, a spring 1520 is interposed between the head 1120 and the upper cap 30, and the spring 1520 may elastically support the hour hand channel bundle B downward.

A slide rail 1115 is formed along the outer circumferential surface of the channel coupling portion 1110 of the bundle body portion 1100, and side projections 1213 of the hour hand channel 1200 are fitted to the slide rail 1115, respectively. The hour hand channel 1200 is radially equally divided and coupled to the channel coupling part 1110 over the entire circumference of the outer circumferential surface of the channel coupling part 1110.

As such, according to the exemplary embodiment of the present invention, since the hour hand channels 1200 are attached to the outer circumferential surface of the bundle main body 1100, the more hour hand channels can be attached. That is, in the conventional hair implanter, the bundle main body is configured in a magazine shape to put the hour hand channel in the inner space of the bundle body part, but according to the embodiment of the present invention, since the diameter of the case 10 is attached along the outer circumferential surface of the bundle body part, In the same case, more hour hand channels can be combined in the same space than in the related art.

6 and 7, the hour hand channel 1200 may be formed in the body part 1210 in a direction opposite to the side protrusion 1213 of the body part 1210, that is, in a radially outward direction of the hour hand channel bundle B. It includes an extended protrusion engaging portion 1211. The locking protrusion 1211 is formed at a lower end of the slot 1215 formed in the vertical direction, a protrusion 1217 extending to protrude further radially outward from the surface of the locking protrusion 1211, and the locking protrusion 1211. Toothed ratchet gear 1212 having a tilt angle only.

The slot 1215 is formed in a vertical direction on the radially outward surface of the locking protrusion 1211 and communicates with the tubular internal space of the body portion 1210. The mandrel 1230 is disposed in the tubular inner space, and the lever 1231 is coupled to an upper end of the mandrel 1230. The lever 1231 is guided by the slot 1215 and may slide up and down. A spring 1241 is fitted around the mandrel 1230. The upper end of the spring 1241 is supported by the lower surface of the lever 1231, and the lower end of the spring 1241 is a stepped portion between the first diameter portion 1210a and the second diameter portion 1210b in the body portion 1210. Is supported.

The upper end of the slot 1215 is open, and the upper end cap 1250 may be fitted to the open upper end. The upper stopper 1250 serves as a stopper so that the lever 1231 does not go upward any further. As shown in FIG. 10, the upper surface of the upper plug 1250 has a surface inclined in one direction so that the hour hand channel bundle B can rotate smoothly. That is, the surface 1251 of the upper plug 1250 is rotated in the direction of the hour hand channel bundle so that the rotation of the hour hand channel bundle B is not hindered by the push bar 1530 that is in contact with the upper surface of the top stopper 1250. As a result, it is formed as an inclined surface inclined by a predetermined inclination angle 1253.

The body portion 1210 of the hour hand channel 1200 further includes a locking groove 1219. The locking groove 1219 is formed below the locking protrusion 1211 on a surface facing toward the radially outer side of the body portion 1210. The locking groove 1219 may accommodate the latch 1910 of the hour hand channel locking portion 1900. A detailed shape and function of the locking groove 1219 will be described later with reference to FIGS. 14 and 15.

Meanwhile, as shown in FIGS. 2 and 3, the hair implanter includes a push bar 1530 that pushes one of the hour hand channels 1200 of the hour hand channel bundle B downward. The push bar 1530 is elastically coupled to the upper cap 30 through an elastic member such as a spring 1540 and is arranged to press one tack channel 1200 of the tack channel bundle B from the top to the bottom. . The push bar 1530 and the nozzle 21 are arranged aligned on the same vertical line, so when the push bar 1530 pushes the hour hand channel 1200 downward, the needle 1220 of the pushed hour hand channel 1200 is pushed. ) May protrude by a predetermined length through the nozzle 25.

11 illustrates a mandrel catch 1700 according to one embodiment. A mandrel stop 1700 is disposed on the radially outer side of the hour hand channel pushed downward by the push bar 1530. In the illustrated embodiment, the mandrel stop 1700 is installed on one side of the case 10. The mandrel catch 1700 temporarily stops the movement of the mandrel 1230 in the hour hand channel 1200 while the hour hand channel 1200 is pushed down by the push bar 1530 and then rises again. do.

Referring to the drawings, the mandrel catch portion 1700 has a clasp 1710, a clasp receiving portion 1720 for receiving the clasp 1710, and an elastic member interposed between the clasp 1710 and the clasp receiving portion 1720 ( 1730).

The clasp receiving portion 1720 may be bolted and fixed to one side of the case 10 through, for example, bolt grooves of the extension regions 1723 on both the left and right sides thereof. In this case, the bolt groove of the clasp receiving portion 1720 may have a rectangular shape, whereby the position of the clasp 1710 may be adjusted. The position of the clasp determines the length of the mandrel 1230 protruding out of the nozzle 25 during hair follicle insertion, thereby affecting the depth of the hair follicle being planted. The clasp receiving portion 1720 has a space in which the clasp 1710 can enter, the elastic member 1730, such as a spring is interposed therein. Accordingly, the clasp 1710 is disposed within a distance that interferes with the vertical movement of the lever 1231, and is configured to elastically retract in the radially outward direction of the hour hand channel bundle B.

When no force is applied to the clasp 1710 The clasp 1710 protrudes from the clasp receiving portion 1720 (in the radially inward direction of the hour hand channel bundle B) so that the lever 1231 slides up and down. It comes in contact with the lever 1231. At this time, as shown in Fig. 11A, the upper side of the contact surface of the latch 1710 in contact with the lever 1231 is inclined upward and the lower lever contact surface 1711 is formed substantially horizontal. Therefore, when the lever 1231 descends from the top of the latch 1710, the lever 1231 may descend while pushing the latch 1710 toward the clasp receiving portion 1720 side, but the lever 1231 is the latch 1710. The upper surface of the lever 1231 is caught in contact with the lever contact surface 1711 of the latch 1710 when rising from below to the lever 1231, so that the lever 1231 can no longer rise.

Meanwhile, a protrusion 1217 protruding in the radially outward direction of the hour hand channel bundle B is formed at a side surface of the slot 1215 of the hour hand channel 1200. The protrusion 1217 is the same as the lever 1231 in the radially outward direction or protrudes more outward than the lever 1231. In addition, the clasp 1710 has the left and right widths of the clasp 1710 set to interfere not only with the lever 1231 but also with the vertical movement of the protrusion 1217, and the clasp 1710 in contact with the protrusion 1217 as shown in the drawing. ), The upper side of the contact surface is inclined upward and the lower protrusion contact surface 1713 is also inclined downward. Thus, in any case where the hour hand channel 1200 rises from the bottom of the clasp 1710 upwards or downwards from the bottom, the protrusion 1217 pushes the clasp 1710 toward the clasp receiving portion 1720 side. Can rise / fall.

A locking and releasing operation of the mandrel 1230 by the mandrel locking unit 1700 having the above-described configuration will be described with reference to FIG. 12.

FIG. 12A illustrates a state before the hour hand channel 1200 attached to the hour hand channel bundle B descends. In this state, the lever 1231 and the protrusion 1217 of the hour hand channel 1200 are both located above the latch 1710 of the mandrel stop 1700.

When the push bar 1530 pushes the hour hand channel 1200 downward, the hour hand channel 1200 descends downward. Since the projection 1217 and the lever 1231 contact the inclined surface of the clasp 1710 when the hour hand channel 1200 descends, pushing the clasp 1710 toward the clasp receiving portion 1720 side and The lever 1231 may be lowered.

As shown in Fig. 12B, when the lever 1231 is lowered lower than the latch 1710, the lever 1231 is raised upward by the spring 1241 without lowering, but the lever 1231 is lowered. ), The lever 1231 is caught by the latch 1710 while the upper surface of the) contacts the lever contact surface 1711 of the latch 1710.

Then, when the hour hand channel 1200 ascends, as shown in FIG. 12C, because the lever 1231 is locked to the latch 1710, the lever 1231 and the mandrel 1230 integrally coupled thereto are Can not rise.

When the hour hand channel 1200 further rises, as shown in FIG. 12D, the protrusion 1217 contacts the clasp 1710 and pushes the clasp 1710 toward the clasp receiving portion 1720. Accordingly, the latch 1710 is retracted toward the clasp receiving portion 1720 to release the latch on the lever 1231, and the lever 1231 and the mandrel 1230 are raised by the elastic force of the spring 1241. It can return to the state similar to 12 (a).

As such, according to one embodiment of the present invention, the return of the mandrel 1230 has been solved by a novel mechanical structure. Conventionally, a separate driving means such as a driving motor was required for the return of the mandrel 1230, but according to the present invention, since a drive motor for the return of the mandrel 1230 is not required, the technical cost and device complexity are significantly reduced.

On the other hand, the side of the lifting gear holder 1400 protrudes in the radially outward direction of the case 10 is attached to the hour hand channel locking portion 1900. The hour hand channel catching part 1900 is pushed by the push bar 1530 to walk down the one hour hand channel 1200 so that the hour hand channel 1200 follows the up and down movement of the elevating gear holder 1400 to move together. Device.

13, 15, and 16, the hour hand channel catching portion 1900 includes a clasp 1910, a clasp receiving portion 1920 for receiving a clasp 1910, and a clasp 1910 and a clasp receiving portion 1920. It may be composed of an elastic member 1930 interposed between.

The clasp receiving portion 1920 may be coupled to and fixed to the connecting piece 1420 by, for example, a coupling method such as bolting. The clasp receiving portion 1920 has a space for the clasp 1910 to enter therein, the elastic member 1930, such as a spring is interposed therein.

The clasp 1910 may be engaged with the locking groove 1219 of the hour hand channel 1200 as a hexahedral member. As shown in FIGS. 15 (a) and 16, respectively, when the hour hand channel locking part 1900 is viewed from the left and the top, respectively, the right step part 1219c and the lower step part ( 1219b is formed at right angles, and the stepped portion (ie, the left stepped portion 1219d in the illustrated embodiment) and the upper stepped portion 1219a in the direction of the inclination angle of the ratchet gear 1212 are chamfered to be gentle inclined surfaces. It is. In addition, each of the four corners of the protruding end of the clasp 1910 in contact with each step of the engaging groove 1219 is also formed at right angles or chamfered to form an inclined surface. That is, the right and bottom edges of the four protruding edges of the clasp 1910 are formed at right angles, and each step portion (ie, the left step portion 1219d in the illustrated embodiment) is formed at the inclined surface of the engaging groove 1219. ) And the corners of the clasp 1910 (ie, the left and top corners in the illustrated embodiment) which are in contact with the upper stepped portion 1219a are chamfered to form an inclined surface. The right step 1219c of 1219 and the right edge of the corresponding clasp 1910 may be formed at right angles or may be formed as an inclined surface.

With this configuration, the hour hand channel 1200 moves together with the vertical movement of the elevating gear holder 1400 in the locked state in which the latch 1910 is inserted into the locking groove 1219. However, in this latched state, when the hour hand channel bundle B is rotated counterclockwise as shown in Fig. 16, the latch 1910 is retracted toward the clasp receiving portion 1920 to release the jam, and the hour hand channel bundle B When rotated by one channel, clasp 1910 latches another hour hand channel 1200.

Meanwhile, as shown in FIG. 16, the edge 1219e of the body portion 1210 adjacent to the right side surface 1219c of the two side surfaces of the locking groove 1219 among the body portions 1210 of the hour hand channel 1200 is shown. Can be formed by chamfering or rounding. Therefore, when the hour hand channel bundle rotates by one channel, the latch 1910 may smoothly rotate without being interfered with or interfered with the edge of the body portion 1210 of the hour hand channel.

According to the hour hand channel latching unit 1900 according to the present invention, whenever the hour hand channel bundle B rotates by one channel every time, a locking and releasing operation for one hour hand channel 1200 is automatically performed. In addition, the hour hand channel 1200 caught in the clasp 1910 can be moved together by following the up and down movement of the elevating gear holder 1400, and the needle is pressed when the user presses down the handle to insert the needle into the scalp. It can prevent the retreat into the inside.

17 to 19, a manual operation knob 1800 for moving the elevating gear holder 1400 in the up and down direction will be described. FIG. 17 is a perspective view illustrating a coupling structure of the manual operation handle 1800 and the case 10, and FIGS. 18 and 19 are cross-sectional views of portions of the hair implanter equipped with the manual operation handle, respectively, viewed from different directions.

Referring to the drawings, the manual override handle 1800 has a shape that at least partially surrounds the outer circumferential surface of the case 10. The outer surface of the handle 1800 is formed with an uneven shape so that the operator's fingers do not slip, may also include one or more protrusions (1850).

The handle 1800

A spring accommodating part 1820 for accommodating an elastic member, such as an upright direction, may be included on one side. The spring 1830 may be received in the spring receiving portion 1820 in a state of being inserted into a spring undercoupling member 1840 that at least partially surrounds the spring 1830. As shown in FIG. 18, the upper end of the spring 1830 is fixed to the upper portion of the spring receiving portion 1820 and the lower end is fixed to fixing means such as a bolt 1860 of the spring lower coupling member 1840. And the spring lower coupling member 1840 is coupled to the case 10 by a bolt 1860.

By such a configuration, when the user grasps the manual operation knob 1800 and rises, the spring 1830 increases and a tension force for pulling the handle 1800 and the case 10 acts, so that the spring 1830 when the external force is lost. By the pull force of the manual operation handle 1800 can be lowered to return to the original position.

In addition, although the spring 1830 is used as an example of the elastic member in the illustrated embodiment, any elastic member having elasticity, such as a rubber band, may be used instead of the spring 1830, and may be replaced with a compressive elastic member such as a compression spring. Of course.

Now, with reference to Figure 20 will be described the hour hand channel rotation operation by the channel rotation means. In FIG. 20, for convenience of explanation, a part of the ratchet support part 1300 and the lifting guide 1350 and the lifting gear holder 1400 (dotted line) formed on the inner surface of the case 10 and two hour hand channels 1200 adjacent to each other are shown. Only ratchet gear 1212 is shown schematically.

In FIG. 20A, the lifting gear holder 1400 is lower than the upper surface 1310 of the ratchet support 1300 by the spring 1830 when no external force by the user acts on the lifting gear holder 1400. The ratchet gears 1212 of the hour hand channel bundle are positioned on the upper surface 1310 of the ratchet receiving part 1300 and are supported by the spring 1520. However, at this time, the one hour hand channel 1200 pushed downward by the push bar 1530 is in a state of being lowered by being caught by the hour hand channel catching part 1900, but is not shown in FIG. 20.

On the other hand, the uppermost end 1410b of each of the wedge-shaped protrusions 1410 of the elevating gear holder 1400 is the end 1313c and the end 1310c of the uppermost end 1310c of the upper surface 1310 of the ratchet base 1300 when viewed from the side. Is located between).

When the user grabs the manual override knob 1800 and lifts it upward, the lifting gear holder 1400 also rises with the knob 1800. As the elevating gear holder 1400 gradually rises, the inclined surface 1410a of the wedge-shaped protrusion 1410 of the elevating gear holder 1400 as shown in FIGS. 20 (b) and 20 (c) becomes the hour hand channel 1200. The tacking channel bundle B is raised overall as it comes into contact with the ratchet gear 1212. At this time, the tacking channel bundle B tries to rotate while sliding down along the inclined surface 1410a of the wedge-shaped protrusion 1410 by the elastic force of the spring 1520, but the ratchet gear 1212 is a wedge-shaped protrusion 1410. Since the inclined surface 1410a and the vertical surface 1310b of the ratchet base portion 1310 are supported while being supported, the hour hand channel bundle B cannot be rotated, but only rises by the elevating gear holder 1400.

However, if the elevating gear holder 1400 is raised until the wedge-shaped protrusion 1410 is higher than the upper surface 1310 (Fig. 17 (c)), since the support by the vertical surface 1310b of the upper surface 1310 is lost. As the ratchet gear 1212 slides down along the inclined surface 1410a of the wedge-shaped protrusion 1410, the hour hand channel bundle B rotates by a predetermined angle (Fig. 20 (d)).

Then, when the user releases the force that lifts the handle 1800, the handle 1800 is lowered by the spring 1830, and the lifting gear holder 1400 is also lowered together with the ratchet gear 1212 of the hour hand channel 1200. ) Touches the inclined surface 1310a of the ratchet support upper surface 1310 (Fig. 20 (e)). When the wedge-shaped protrusion 1410 of the elevating gear holder 1400 descends below the upper surface 1310 of the ratchet support portion, the ratchet gear 1212 slides down along the inclined surface 1310a of the upper surface 1310 and tackles the hour hand. The channel bundle is again rotated by a predetermined angle (Fig. 20 (f)). Therefore, the hour hand channel bundle B rotates by one channel during the operation of FIGS. 20 (a) to 20 (f).

As described above, according to the channel rotating means according to the embodiment of the present invention, each time the lifting gear holder 1400 is raised and lowered once, the hour hand channel bundle may be rotated by one channel, and the needle of the other hour hand channel is changed every time. Since the 1220 may be discharged to the nozzle 21, each time the user manually moves the handle 1800 up / down, the needle 1220 may be changed one by one to perform continuous hair transplantation.

As described above, various modifications and variations are possible to those skilled in the art to which the present invention pertains.
